Just a few more impressions. Used the M6 for video over Christmas. Worked flawlessly. Even at high ISO, I am very impressed. Tracked my nieces running around very well.

I have taken a few stills with it, where it does seem very good. As expected, I do not see it replacing my 5DIV. But given how much I am liking the ergonomics, if Canon were to release a higher end general purpose zoom for the M-mount, I'd probably pick it up. The 18-55 that I use is good, but there is room for improvement with 32 MP. I haven't tested my other lenses, which I'll do at some point this winter.
